FS#645 - E resolution is fucked sometimes

If you run something like “berusky” (small game, which don’t works in fact), it fucks your X resolution without possibility to recover it (BIG BAD BUG)

In short it seems like to: change your E resolution, don’t restore the original one, but E saves and remebers it

We should need a way to detect that the resolution was changed by FOO, when FOO finishes and some seconds passed change the resolution to the original one if we are not on it (not sure if this is possible)

Also, is needed to save the resolution on E confs only when we select to save it, seems like there’s a trigger that saves it automatically, this is very bad :P

Notes: betatest in e19 to see if the bug is solved (and so just cherry-pick the fixes)

Don't forget to fork Berusky I (asokoban/bugs escape, Anakreon.cz) for fit purpose by tagging it source-only for the version somehow?

It's not actually fun to pass arguments to arandr from an alt-F2 console to fix this, but it lets you unclench faster, I should think. But E19 should change it with alt-grave-[backlight-down] right..no, that's my down key anyhow, just as bad as X11's ctrl-alt-numpad+. Alt-greve-end-Hscroll (on a trackpad?) Overload ctrl-alt-backspace again? Gesture control to squeeze cheeks of monitor until it comes 'round?
